This invention relates to radiators and particularly 7 to; humidifying radiators equipped with-waterevaporatin sections of the kind described'in. my co-pen ing applica- 8 tion Serial No. 537,786, filed May. 16, 1931.

More particularly, .the present invention. provides certain improvements in the design of the water evaporating sections where the evaporating efficiency of each section is increased in substantial degree. It also pro vides for a sloping arrangement of the sections which accelerates the upward flowof; heated air between the sections; lends itself to effective concealmentof the water courses without the use of a cabinet; and enables the width of the evaporating area of each section to be increased to a maximum degree for a given width of floor surface.

Proceeding now to a more detailed descripno tion oftheinvention reference will be had to the accompanying drawings wherein Fig. 1 is a perspectiveview of a humidity ing radiator constructed in accordance with this lnvent on.

The preferred embodiment of the invention is illustrated in Figs. 1 to 7 inclusive. It comprises a series of hollow radiator sections A arranged one abovethe other. in vertical alignment, the lowermost sectionbeing sup- 6 ported on suitable legs 11 andthe uppermost Fig. 8 is a plan viewof a'modified type of section being equipped with a removable.

g grill 12. Eachsection islprovided' at the top with an evaporating area including a long, tortuous water course offrelatively' narrow channel width. This water course is formed-by shaping the top wall Mot each section to provide asries of relatively narrow parallel flow channels '(B,- G, D, E, F, G, H and I) extending in the longitudinal direction j of thesect-ion. The channels B, D,F-and- H" i slope-downwardly toward one end ofthesection as" viewed in Fig. 3 while the alternate channelsnC, E, G and I slope downwardly toward the opposite end of the section. The

.low end of each channel is in communication i a with the high end of the next lower channel so 4 that a film of water traversing the water course afforded bythese channels is caused to flowba'ck andforth anumber of times-along it the upper'surface of the wall lbetore reach ing t e outlet 15 at'the low endof the lower- 1 most channel I.

Each section A is also provided with two series of pond-forming pockets located at y a ,f-oppositeends of the'top wall 14. Thepockets i Fig. 2 is a transverse, sectional view along of one series are designated by reference char: acters.16, 17, 18-and 19 and those ofthe're mainingseries byreferencecharactersf2'0 21 the pocket 16 and flows as a narrow film through the channel Bto the pocket 20 and then-back a through the channel C to the pocket 17 ,From the p ocket 17 the water flows through the channel D to the pocket 21 and back" Lthrough :the channel E to the pocket 18. 5 .From the pocket 18 the flo wis through the drain conduit 25 extending toward the opposite or rear sideof the section. The discharge a end of each conduit 25, with-the exception of the conduit of thelowermost section, is positioned so that the water passing therethrough is delivered into the pocket 16 of the next lower "section A, the conduit 25 of the lower mostsection being connected to a drain pipe 1 5 through a drip valve having its discharge positioned directly above the pocket 16 of the uppe'rmostlsection A. It has not been considered necessary to show this drip valve In the present instance since the arrangement thereof will preferably be the same as described in my prior application Serial No.

The coupling of the sections A to provide for the circulation of heating fluid throu h the internal passages-A is accomplished sud)- stantially in accordance with standard practice. Each section is provided with vertical nipple receiving bosses 27 and 28 projecting upwardly from the top wall 14 in line with similar bosses 29 and 30 projecting downwardl from the bottom wall 31. The angular relationbetween the bosses and the top and bottom walls of each section is such that, in assembled relation of the sections (see Fig. 2) thebody of each section is sloped so that the general plane of its top and bottom walls'is inclined with respect to thehorizontal.

This parallel sloping or downward inclination of the sections toward the front of the radiator assembly has several important advantages. It substantially conceals from view the water course at the top of each section with the exception of the uppermost water course which is concealed beneath the covering grill 12 it provides upwardly inclined air passages 33 which serve to accelerate the natural upflow of heated air between the sections, A and produces a corresponding in- 40 crease in the rate of evaporation; it enables the sections to be provided with evaporating areas of greater width than the width of the floor space occupied by said sections and it also tends to increase the rate of evaporation by accelerating the downward flow ofwater in the channels of the various water courses. The sections A are secured together in their assembled relation by standard connecting nipples (not shown) coupling the lower bosses 29 and 30 of each section tothe upper bosses 27 and 28 of the next lower k section.

The foregoing embodiment of the invention has other advantages in addition to those previously mentioned; The width and arrangement of the channels comprising the water course of each sectionprovides the optimum conditions for evaporation by causing the water to, flow in the form of a narrow rapidly moving film which repeatedly traverses the length of'the evaporating surface while advancing over the width of said surface to the drain outlet. and, consequently, the rate of evaporation 55 is also favorably influenced by the pond- The rapidity of flowforming pockets provided at opposite ends of the flow channels. The accumulation of water in these pockets provides for the creation of a certain head pressure at the high end of each channel which naturally accelerates the downward movement of the film traversing said channel.

The bottom walls of the flow channels of each section may be made perfectly smooth and flat throughout their length but I prefer to provide the longitudinal corrugations indicated at 34. These corrugations serve to increase the area of evaporating surface presented by each channel without seriously impeding the flow of the film or promoting the accumulation of-dirt since the valleys between the ridges of the corrugations extend in the direction of movement of the film so that any sediment deposited-in these valleys is gradually moved along to the outlet.

When the evaporating capacity of all the sections'A is not required the evaporating surfaces of one or more sections may be bypassed as indicatedin Fig. 7. In this in stance the water passing through-the drain conduit 25 of the uppermost section A is delivered through a by-pass connection 35 to the pocket 16 of the lowermost section so that the intermediate section functions-merely as a heating section. As herein shown the bypass connection 35 is in the form of an appropriately curved tube having its receiving A end detachably secured in any desired way to the discharge end of the associated conduit 25. p

Each section A is formed to present end Walls A of rectangular outline having horizontal upper edges A projecting above the top wall 14 and horizontal lower edges A projecting below the bottom wall'31. The outer side wall of the channel B of each section is also formed as an upward extension of the rear body wall'A and merges with the contiguous portions of the end walls A so that its upper edge A is a continuation of the edges A. These are not essential features of design but tend to improve the general appearance of the radiator as will be apparent from inspection of Fig. 1 wherein it will be noted that the water courses are substantially concealed at the ends of the radiator by reason of the fact that the upper end edges A of each section closely approach the lower end edges A of the next upper section.

In the present instance the upwardly projecting portions of the walls A and A are utilized, in connection with the bosses 27 and 28, the ribs A and the upwardly projecting portion A. of the front wall 'A", to provide the confining walls of the previously mentioned pond-forming pockets, The front wall portion A forms the outer side wall of the lowermost channel I and its upward projection is limited so as not to seriously obstruct the air passage 33.

In Figs. 8 and 9 I have shown a modified radiator section embodying substantially the same principles of water-course construction. In this instance the radiator section 37 is formed with a central elongated air passage v 38 and a spiral water course 39. The water course has its inception at the point 40 and is spiralled around the airpassage 38 a number of times during its descent to the outlet 41 through which the water drains into the *drain conduit 42. This construction also produces a narrow rapidly descending film of water which is guided back and fortha number of times along the length of the secranged one above the other in vertical align ment. I

3. A radiator comprising a series of vertically spaced hollow radiator sections, each having'its topwall recessed to provide a. water evaporating area and being inclined downwardly toward the front of the radiator to hide the evaporating area of the next lower section.

4. A hollow radiator section presenting top and bottom walls sloping downwardly toward the front of the section when the latter is supported in its operative position, the end walls of said section being of rectangular outline presenting horizontal upper and lower edges projecting, respectively, above and below the said top and bottom walls.

5. A hollow radiator section presenting top and bottom walls sloping downwardly toward the front of the section when the section is supported in its operative position, the top wall of said section being recessed to provide a water evaporating area and the end walls being formed to present upper horizontal edges projecting above the top wall and lower horizontal edges projecting below the bottom wall.

6. A radiator including a series of vertically spaced radiator sections, each having its top and bottom walls sloping downwardly toward the front of the radiator, the end walls of each section rejecting above the top wall and below the ottom wall and having their upper and lower edges closely approaching the opposing end Wall edges of adjacent sections.

7. A radiator including a series of vertically spaced radiator sections, each having its top and bottom walls sloping downwardly toward the front of the radiator, the top wall of each section being" recessed to provide a water evaporating area and the end walls being formed to project above the top wall and below the bottom wall so that the upper and lower edges of said end walls closely approach the opposing end wall edges of adjacent sections.

8. A radiator including a series of vertically spaced radiator sections, each having its top wall formed to provide a water course having an outlet through which the water normally drains into the water course of the nextlower section and a by-pass conduit adapted to be connected to the outlet of a selected section to deliver the water draining through the outlet to a section other than the one immediately below the said selected section.

In witness whereof I have hereunto set my hand.
